3 Claims.

This invention relates to a hinge for hingedly connecting two memberstogether, of the general class havin pintles and channeled knuckleswhich engage with each other, and to a method for hingedly connectingtwo members together.

Hinges of this general class have been provided in the past. In order toconnect two members together with them, however, it has, to myknowledge, always been necessary to connect them first at one pointalong the edge to be joined, and subsequently to connect them at aspaced apart point. Connecting members in this way is relatively awkwardand lirnits the applicability of the construction.

I have invented a hinge of this class which has a wider applicability.

It is an object of the invention to provide a hinge, the leaves of whichcan be caused to engage with each other by causing the channeledknuckles to engage with the pintles simultaneously at all points alongthe edges to be connected, and which will lock together so thatdisengagement is impossible upon slight rotation.

It is a further object of this invention to provide a hinge having theabove-mentioned characteristics which is cheap to manufacture.

With these and other objects in view, a hinge according to my inventioncomprises two similar leaves, each having a base for mounting it, apintle carried by said base, and a knucklecarried by said base in spacedapart relation to said pintle. The knuckle is formed with a channel, thelongitudinal axis of which aligns with the longitudinal axi of thepintle. The hinge and the method for hingedly connecting two memberstogether, according to my invention, will be apparent after reference tothe following detailed specification read in conjunction with thedrawings.

In the drawings:

Figure 1 is a View showing two members about to be hingedly connectedaccording to the present invention,

Figure 2 is a view showing the same two members hingedly connected,

Figure 3 is a sectional view showing the relation of the pintle and acc-operating knuckle im mediately after they have been brought together,

Figure 4 is a sectional View showing the pintle and the knuckle afterthey have been rotated.

Referring to the drawings, a complete hinge according to my inventionwill be seen to comprise a leaf Ill and leaf N having bases [2 and I3respectively for mountingthem on the edges of members [4 and [5 that areto be hingedly connected together. The leaf H3 is similar to the leaf lI in construction and like numerals on each leaf refer to like parts inthe portions of the specification that follow.

Each of the leaves will be seen to have a pintle it carried betweenspaced apart shoulders [land it which are supported by arms l9 and 20 onthe base 12, and a knuckle zl also supported by the arm 22 on the baseE2. The knuckle 2| in the embodiment of the invention shown is formedwith a channel 23 bybending the upper extremity of the arm 22 in asubstantial U shape. The longitudinal axis of the channel 23 aligns withthe longitudinal axis of the pintle 1'8 and the cross section of thechannel 23 is designed to rotatably engage with the pintle l 6 of aco-operating leaf. The shoulders ill and I8 arev spaced apart to snuglyreceive therebetween a knuckle of a co-operating leaf.

The method for connecting the members M and it together will be apparentfrom the drawings. The knuckle 2i and pintle it carried by the base l2are mounted on the member Hi asshown, and the corresponding knuckle andpintle carried by the base l3 are mounted on'the member [5. The

members It and i5 are then rotated to cause the mouths of the channels-23 formed in each of the knuckles to face each other so that the leavesIll and l I can be brought into engagement with each other whereby tocause the knuckle of each leaf to engage with the pintle of the other.After the leaves have been so brought into engagement with each other,it is merely necessary to rotate one of the members with respecttotheother. Upon rotation of the members M and 15 with respect to eachother it will be apparent that the mouths of the channels formed in theknuckles 2| will no longer face each other, and that each channel willlock with the pintle it engages to prevent the two members from parting.

The channel 23 is formed with one of its sides extended as at 24 to aidthe locking function of the knuckles.

In use stop means for preventing the members it and i5 from returning tothe position in which the leaves it and H can disengage can be employed.It will further be apparent to those skilled in the art that the leavescould be designed by changing the angl of the channels 23 with respectto the bases so that they could be united when the members M and [5 areat any predetermined angle with respect to each other.

In the drawings I have shown a single leaf having the knuckle and pintlemounted on it. It will be apparent, however, that a separate leaf couldbe formed for the pintle and for the knuckle.

Embodiments of my invention other than the 3 one shown in the drawingswill be apparent to those skilled in the art. I do not intend,therefore, that the scope of my invention should be limited by theforegoing specification except by the limitations expressed in thefollowing claims.

What I claim as my invention is:

l. A hinge leaf, for co-operation with a similar hinge leaf, comprisinga base having three spaced apart arms extending therefrom, the upperextremities of two of said arms that are adjacent each other beingformed into shoulders, a pintle extending between said two shoulders,the upper extremity of the remaining arm being formed into a U shape toform a channeled knuckle, said channel having its longitudinal axisaligned with the longitudinal axis of said pintle, said shoulders beingspaced apart to snugly receive therebetween a knuckle equal in length tothe length of said above-mentioned knuckle, said channel formed in saidfirst mentioned knuckle being designed to engage with a pintle havingdimensions similar to said above-mentioned pintle.

2. A hinge leaf for co-operation with a similar hinge leaf to form ahinge, comprising a base for mounting said leaf, a pintle carried bysaid base, and. a knuckle carried by said base in spaced relation tosaid pintle, said knuckle being formed with an open channel, thelongitudinal axis of said channel being aligned with the longitudinal.axis of said pintle, said channel 4 formed in said knuckle having alength that corresponds to the length of said pintle to engage with apintle on a similar hinge leaf having a pintle dimension similar to saidfirst mentioned pintle.

3. A hinge leaf for co-operation with a similar hinge leaf, comprising abase, two spaced apart shoulders carried by said base, a pintleextending between said two shoulders, a knuckle carried by said base,said knuckle being formed with a channel having its longitudinal axisspaced from and aligned with the longitudinal axis of said pintle, saidshoulders being spaced apart to snugly receive therebetween a knuckleequal in length to the length of said above-mentioned knuckle, saidchannel formed in said knuckle being designed to engage with a pintlehaving dimensions similar to said above-mentioned pintle.
